I just tried VGA and I am not getting anything displayed. PC is working with your code.
I will need to check my wiring but not tonight

VGA and Brian's LA work as I tried it already. This is my setup:
P0-->HSYNC
P1-->BLUE
P2-->GREEN
P3-->RED
P4-->VSYNC

Just wire up the grounds and connect to these pins directly and it will work, especially as Brian's code runs on a P2D2 like yours.

Yes, that is how I thought I had wired it. GND is just above the P0/P1 pair.
If the cable meters ok, I'll try another monitor. I am using an Acer X233H 23". Perhaps it's not recognising the auto switch (might require 3V3/5V on the power pin 9)

Brian,
I've just run up P123_A9_LA.exe on Wine and it gives me a baudrate error, see attached, that seems at odds with experience. Or at least Linux programs don't have the same restriction. I guess Wine might be filtering the setting.

Is that due to a query in your code? If so, I'd like to try a hack where it just specifies the desired rate and hoping it works.

"We suspect that ALMA will allow us to observe this rare form of CO in many other discs. By doing that, we can more accurately measure their mass, and determine whether scientists have systematically been underestimating how much matter they contain."

Oh, just found the later zip file with P2_LA_control_3.exe in it. That's happy with comport as long as I use 115200 baud. I'll assume that's a usable rate ...

EDIT: Except I've only got a P123 board.

"We suspect that ALMA will allow us to observe this rare form of CO in many other discs. By doing that, we can more accurately measure their mass, and determine whether scientists have systematically been underestimating how much matter they contain."

Thanks Brian. Did that and it's running 3 cogs with a couple of green leds alternately flickering ...

Loading up the LA_Control program on Wine and click Open Port and bam, the FPGA Prop2 resets. I'm guessing the DTR line gets pulled.

Clicking RUN and I see Tx led flicker. But, since the Prop2 is now sitting idle, there is no reply.

"We suspect that ALMA will allow us to observe this rare form of CO in many other discs. By doing that, we can more accurately measure their mass, and determine whether scientists have systematically been underestimating how much matter they contain."

Got past that hurdle - I loaded the .obj file as BOOT_P2.BIX onto a uSD card and used the experimental SD boot wiring to auto load up on reset.

Sadly clicking on RUN or INFO produced no display. Wine is reporting a slow stream of "004f:fixme:comm:wait_on EV_RXFLAG not handled" messages when doing so.

Think I'll be leaving it there.

Here's a test code sample of exercising a smart pin in transition mode.
It include the use of a pins selector capability to read an nearby pins state.
Also the use of a marker signal.

Got a match here using Wine and also inserting backslash into all LOC instructions:

PS: I think it was always working with Wine - with nerf'd comport function. I just wasn't giving the upload enough time to complete at 115k baud. I kept on clicking buttons because it didn't show any progress.

"We suspect that ALMA will allow us to observe this rare form of CO in many other discs. By doing that, we can more accurately measure their mass, and determine whether scientists have systematically been underestimating how much matter they contain."

Dave had to resort to using a cross-platform library, I think, to make >115k work transparently for his loadp2 tool ...

EDIT: Sort of. Looks like a bunch of people involved to get that right. Dave Hein has used osint_*.c files that have been updated by David Betz but appear to be originally written by a John Denson.
